It looks like you are NOT using ssh to get into the app01, app02, app03 and app04 hosts, but simply applying the various ip addr add
commands on the jumphost. This can’t work, and is probably your problem. You need to, for each of the four hosts:
- ssh into the right host
- run the right
ip addr add
commands on that host. - repeat for the other 3 hosts.
The question referred to how to set up the configuration. It should be updated on app01-04, not on the jump host.
